Set-MailboxExportRequest

Use the Set-MailboxExportRequest cmdlet to change export request options after the request has been created. You can use the Set-MailboxExportRequest cmdlet to recover from failed export requests.

Note:

This cmdlet is available only in the Mailbox Import Export role, and by default, that role isn't assigned to a role group. To use this cmdlet, you need to add the Mailbox Import Export role to a role group (for example, to the Organization Management role group). For more information, see the "Add a role to a role group" section in Manage role groups.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Import Export" entry in the Recipients Permissions topic.

The Identity parameter specifies the identity of the export request. By default, export requests are named <alias>\MailboxExportX (where X = 0-9). If you specify a name for the export request, use the following syntax: <alias>\<name>.

RehomeRequest

Required

System.Management.Automation.SwitchParameter

The RehomeRequest parameter specifies to the Microsoft Exchange Mailbox Replication service (MRS) that the request needs to be moved to the same database as the mailbox that's being exported. This parameter is used primarily for debugging purposes.

AcceptLargeDataLoss

Optional

System.Management.Automation.SwitchParameter

The AcceptLargeDataLoss switch specifies the request should continue even if a large number of items in the source mailbox can't be copied to the target mailbox. You need to use this switch if you set either the BadItemLimit or LargeItemLimit parameters to a value of 51 or higher. Otherwise, the command will fail.

BadItemLimit

Optional

Microsoft.Exchange.Data.Unlimited

The BadItemLimit parameter specifies the maximum number of bad items that are allowed before the request fails. A bad item is a corrupt item in the source mailbox that can't be copied to the target mailbox. Also included in the bad item limit are missing items. Missing items are items in the source mailbox that can't be found in the target mailbox when the request is ready to complete.

Valid input for this parameter is an integer or the value unlimited. The default value is 0, which means the request will fail if any bad items are detected. If you are OK with leaving a few bad items behind, you can set this parameter to a reasonable value (we recommend 10 or lower) so the request can proceed. If too many bad items are detected, consider using the New-MailboxRepairRequest cmdlet to attempt to fix corrupted items in the source mailbox, and try the request again.

Note:

If you set this value to 51 or higher, you also need to use the AcceptLargeDataLoss switch. Otherwise, the command will fail.

BatchName

Optional

System.String

The BatchName parameter specifies the name of the batch.

CompletedRequestAgeLimit

Optional

Microsoft.Exchange.Data.Unlimited

The CompletedRequestAgeLimit parameter specifies how long the request will be kept after it has completed before being automatically removed. The default value is 30 days.

Confirm

Optional

System.Management.Automation.SwitchParameter

The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.

Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.

DomainController

Optional

Microsoft.Exchange.Data.Fqdn

The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example, dc01.contoso.com.

InternalFlags

Optional

Microsoft.Exchange.Management.RecipientTasks.InternalMrsFlag[]

The InternalFlags parameter specifies the optional steps in the request. This parameter is used primarily for debugging purposes.

LargeItemLimit

Optional

Microsoft.Exchange.Data.Unlimited

The LargeItemLimit parameter specifies the maximum number of large items that are allowed before the request fails. A large item is a message in the source mailbox that exceeds the maximum message size that's allowed in the target mailbox. If the target mailbox doesn't have a specifically configured maximum message size value, the organization-wide value is used.

For more information about maximum message size values, see the following topics:

Valid input for this parameter is an integer or the value unlimited. The default value is 0, which means the request will fail if any large items are detected. If you are OK with leaving a few large items behind, you can set this parameter to a reasonable value (we recommend 10 or lower) so the request can proceed.

Note:

If you set this value to 51 or higher, you also need to use the AcceptLargeDataLoss switch. Otherwise, the command will fail.

Priority

Optional

Microsoft.Exchange.MailboxReplicationService.RequestPriority

The Priority parameter specifies the order in which the request should be processed in the request queue. Requests are processed in order, based on server health, status, priority, and last update time.
Valid priority values are:

Lowest

Lower

Low

Normal This is the default value.

High

Higher

Highest

Emergency

RemoteCredential

Optional

System.Management.Automation.PSCredential

This parameter is reserved for internal Microsoft use.

RemoteHostName

Optional

Microsoft.Exchange.Data.Fqdn

This parameter is reserved for internal Microsoft use.

RequestExpiryInterval

Optional

Microsoft.Exchange.Data.Unlimited

The RequestExpiryInterval parameter specifies an age limit for a completed or failed request. When you use this parameter, the completed or failed request is automatically removed after the specified interval expires. If you don't use this parameter:

The completed request is automatically removed based on the CompletedRequestAgeLimit parameter value.

If the request fails, you need to manually remove it by using the corresponding Remove-*Request cmdlet.

To specify a value, enter it as a time span: dd.hh:mm:ss where dd = days, hh = hours, mm = minutes, and ss = seconds.

When you use the value Unlimited, the completed request isn't automatically removed.

The SkipMerging parameter specifies steps in the export that should be skipped. This parameter is used primarily for debugging purposes.

WhatIf

Optional

System.Management.Automation.SwitchParameter

The WhatIf switch simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.
